I think that is a going to be very complicated. When the line is commented using "--" you are able to match it with "AND NOT LIKE '%--%' ". But when the line is commented using the "/*...*/" block, the comment string doesn't have to be in the same line as the search string.

You probably have to build logic to

first: get the complete text

second: remove all commented text (both between /* ... */ and between -- ... line-end)

finally: search for the searchstring in the remaining text.
